1'4 Q Emu/i ATTORNEY rail 21, so as to clear. the same.

Mounted to slide longitudinally on this rail 26 is a hand grip. The handgrip .comprises a saddle plate 29, having horns 80 upstanding from itsopposite ends and being suitably curved to fit the fingers of the hand,

so that the saddle plate 29 may be easily grasped by the fingers whenthe same are placed over theplate between the horns 30. The forward endofthe saddle plate 29 has a pair of depending lugs 31 provided withregistering vertical slots 32. The rear end of the saddle plate 29 isprovided with a pair of depending ears 33 suitably apertured near theirlower ends. Both the lugs 32 and the ears 33 extend below the guide rail26, which latter passes through the saddle plate. l

Arranged beneath the guide rail 26 and pivotedbetween the cars 83 is acombined locking and connecting lever of bell crank form having onearm34 extending upwardly between the ears 33 and having serrations orteeth in its upper edge adapted to. bite against the lower side of theguide rail 26.

The opposite arm of this operating lever extends longitudinallybeneaththe saddle plate 29 to provide an operating arm 35,

and is flattened and enlarged at itsouter end to provide ahead 36 forthe locking lever.

The head 36 has a lower cam face 37 and has an upper fiat face and avertical substantially central opening 38. The inner end of theoperating lever 35 is provided with a depending lug 39, which isapertured.

The forward end of the saddle plate 29 is provided with a thumb latch.The thumb latch comprises abolt 40 having a head 41, provided inopposite sides with peripherally extending slots through which extends atransverse pivot pin 42 secured through the lugs 31.

The peripheral slots in the head 41 admit of the turning of the bolt 40through nearly 180 degrees. The pivot pin 42 is movable in thevertically extending slots 32 to engage the upper rounded top of thehead 41 against the lower side of the guide rail 26, when the saddleplate 29 is locked to the guide rail.

Surrounding the bolt 40 is a coiled spring 43 bearing at one end againstthe head 41 and at its opposite end against the flat face of the head 36of the operating arm. The

lower end of the bolt 40 terminates in a stem 44, which passes downthrough the opening 38 in the head 36, and is bent laterally beneath thehead, as shown to advantage in Figs. 3 and 6', to-provide a bearing arm45 adapted to ride over the lower cam face 37 of the head 36, draw thebolt 40 downwardly, andlift the operating arm 35. The stem44 is bentupwardly from the outer end of the arm 45 to provide a projection orfinger 46 adapted for engagement by the thumb of the hand when thelatter rests upon the saddle plate 29. When the projection 46 is turnedto extend beyond the forward end of thehand grip, the bearing arm 45engages the highest point of the cam face 37, so as to compress thespring shown to advantage in Fig. 4. The connecting rod 47 is alsoprovided near its forward end with a plurality of longitudinally spacedapart notches 50, which are preferably arranged in the upper side of theconnecting rod adjacentthe side of the cab.

15, as shown inv Fig. 2. A clip 51, in the form of a U-shaped strap,engages about the connecting rod 47, and has, at its inner end, aninwardly projecting tooth 52, for engagement in one of the notches 50,to hold the clip 51 from sliding longitudinally upon the rod 47.

A clamping bolt 53 passes through the outer ends of the clip 51 tocontract the same upon the rod 47, and to also hingedly connect one endof a link 54 to the clip, and to admit of the free swinging of the linktoward and from the connecting rod 47.

The opposite end of the link 54 is provided with a split end 55, theparts of which are bowed outwardly from each other to form a spring head,adaptedto be forced downwardly through an opening in the outstandinglug of a bracket plate 56, secured to the inner side of the door 17. Thehead or open against the tension of thehand grip.

To open the door, the engineer engages his fingers over the saddle plate29 between I compresses the {spring A8,

, and, the toothed arm engage the projection 46. To open the door,

.the projection 46,.is swungforwardly,toward the door, which movementturns. the, bearing ,armit5 overtthe cam face37fand draws the boltAOdownwardly 1 between the lugs .31, and swings the operatin lever towithdrawthe.toothed arm seem; ofcontact with the guide, rails 26.

The hea'dl. of. the bolt-isthus also retracted (from engagement with jthe guide rail 26. :Pressureof, thefingers against the forward horn 30slides the, Saddle plate 29 towardv the door, shifts the connecting rodva7,forwardlythrough the brackets .1;8, and

thrusts. the link,5et.forwardly to swing the door 17' open to thedesired extent.

.The engineermaynow, by drawing theproj ection1a6 backwardly'by thethumb, .re-

leasethespring 43. The spring 43 forces the operating arm downwardly toraise the toothed arm 3% into contact with the guiderail 26, and thenexerts pressure against the head 41130 1110316 it upwardly between thelugs-31 and bind the head against .the guide rail 26. Thus, both thehead 4-1 34 engage againstthe vunder side, of the guide rail 26, andlock it to thehand grip. Pressure against the outer side of,the door 17by ,wind, or the-like, tends to,force.the link 54: and connecting rodat? backwardly. The baokwardrnovement of the connect ng rod at? swingsthe .locking lever to bind-the toothed arm .34

-However,.should a person. in front of the cab 'desireto enter the same,and the hand grip be -locked,, as above described, it is onlynecessaryto grasp the handle 57 a and draw itlforwardly toopen the door. Theoutward movement of the door pulls the link -54and oonnecting rodeiforwardly. This action tends to swing the locking lever and releaseitstoothed arm 3% from contact with spring 43 in opening the door.

The ear 61projects ,laterally from the forward end of the sad dle plate 29, andhasno direct connection with, the operating lever as does the connectingrod t'f oflthe preferred form. v v The arrangement shown in FiglO ispartic arly. rrl ab et th fr m a doo switching engines, by its use, asit is much harder to release or open the door by press- ,ingthereagainst. Then. the engineis traveling backward, thewind blows inthrough tl ebaclrof,the cab andiexerts a pressure upon, the front doorwhich when the preferred form is ,used, is sufficient, to retract theoperating v lever against tei ision of. the ,spring,4l 3,,and permit thedoor to fly open.

Under, such, condition, when the modified arrangement is resorted to,the. mov ment f the r o d 60, ,in eitherdirection, does not iswingi h ping le a i has o nection therewith, and the latter is held incontactwitli, the guide bar 26 by the spring A3 'until manuallyjreleasedby the thumb- ,latch 46. Considerable 7 pressure np'on the rod GO .is,therefore, necessarytoovercome the tension of the spring A3, as. theoperating; lever is moved, only by )ve rcoming the J frictional contactof the arm 34 with the It is, of course, understood that the abovedescribed device is for the right. hand side of a,locomotive cab. Thedevice 'may be made left handedby apparent changes in itsstructuresothat it may be used'on the opposite side of the cab also. It is alsounderstood that the device may be employed for shiftingw1nd0ws,transoms, or any other movable objects to which the device maybe applied, and wherein it is desirable to have a a one-way yieldinglylocking device.

The door 17 may be easily removedby forcing the outer end ofthe link 54Cupwardlyto disengage its spring head 55 from the bracket plate 56 of thedoor. The pintles 19 may now be removed by engaging a fingerthrough theeyes or loopsv20 and drawing the same upwardly. Thus, the doorgmay-bequickly and easily removed from the cab. Thewindow frames 23 may .alsobeeasily removed by forcing the same upwardly against.the tension of theleaf I springs 25 until, the lower ends of the frames 23 are free fromthe lower guide rails 22. The frames 23 are now swung outwardly x anddrawn down to engage the frames from the guide rails.

-The guide rod 26 is preferably given some angular form, such asrectangular, as shown in the present instance, and the saddle plate 29is bent to conform thereto, so that the saddle plate will remain inupright position at all times and will not turn or twist upon the guiderod.

The teeth on the upper end of the short arm 34 of the locking leverpreferably eX- tend in one direction, as shown, in the direction inwhich the arm 34 is swung to release the same from the uide rail.
